EIFECIFICATION forming part of Letters Patent No. 318,416, dated May 19,1885.

Application filed January 2, 1885.

T0 aZZ whom it may concern.-

Be it known that we, WILLIAM H. BURN- HAM and CHARLES H. HALEY, citizensof the United States, residing at Batavia, county of Kane, and State ofIllinois, have jointly invented a new and useful Improvement in Hay-Forks, of which the following is a specification.

Our improvements relate to what is commonly termed double-harpoonhay-fork. The object of our improvements is to overcome certain defectsinherent therein, and to enable us to make an easy-working fork with aminimum amount of material and labor.

In the annexed drawings, which form a part of this specification, Figure1 is a complete side view of our fork with one arm in position to bethrust into the hay, and the other in position to secure the loadthereon. Fig. 2 consists of a complete edge view of same. Fig. 3 is themilled stud-rivet and fulcrum, which will be more fully explainedhereinafter. Fig. 4 is our double-eyed r0pe-guide,which constitutes oneof the features of our invention.

Similar letters of reference indicate corresponding parts throughout theseveral views.

A represents the top or yoke of the frame, formed from flat bar-ironwith curved ends, to which the legs or prongs are secured.

B and B are the prongs, formed by welding two flat bars of iron togetherat one end and drawn out to form the points or thrust-ends of theprongs. The remainder of the prongs throughout are constructed with aspace be tween them to admit of other parts of the mechanism, ashereinafter described.

0 and O are the tie-bars, also used to sustain the eye hereinafterdescribed.

D and D are the levers to trip or look the fork, the upper ends formedto fit the under side of the curved yoke to be protected thereby, andalso to bring them more centrally over the eyes.

E and E are the links that connect the levers with the barbs.

Fand F are the stud-rivets, milled down on each end the proper distanceto pass through the prongs and the tie-bars on each end. Thus we areenabled to rivet the two sides of the prongs rigidly to the tie-bars,and allowing (No model.)

sufficient space between the shoulders to admit of the free use of thisspace for a fulcrum for the levers D and D.

H and H are the barbs, designed, with the aid of the links E and E andthe levers D and D, to secure the load to the fork when thrust into thehay, and to release it when carried to the desired location.

K is the doubleeyed rope-guide, constructed with separate eyes, toprevent the ropes leading to the two levers D and D from becomingtwisted and entangled with each other, as they frequently do when thesingle-eyed guide is used. Where new rope is employed, this difficultydetracts materially from the effective working of the fork, as in theentanglement of the two ropes it invariably happens that one rope willbe shorter than the other and trip one side and leave the other sidewithout tripping, as the shorter rope will receive all of the exertioncommunicated to the tripping-rope by the operator.

L is the trip-rope, communicating with the levers D and D.

M is the manipulating-rope, communicating between the operator and thetrip-rope on the fork.

N and N are the rivets connecting the links E and E with the barbs H andH.

O and O are the rivets used as the fulcrums for the barbs H and H.

Having described the different parts of the fork, as indicated byletters, we will give you the mode of operating the same. Press thelevers D and D down into the position as links E and E to the barbs Hand H, causing 5 them to turn into the position as shown at H in Fig. 1.In this position the fork retains the load untilit is lifted into themow or other desired place. By drawing the rope M the levers D and D aredrawn down into the posi- 10o tion as shown at D in Fig. 1. \Vhen theload is released, the fork may be drawn back to the operator by the ropeM.

Having thus described our invention, what we claim as new, and wish tosecure by Letters Patent, is

1. In allay-fork, the double-eyedrope-guide K, in combination with therope L, and levers D and D, substantially as shown and described.

2. In a hay-fork, the stud-rivet F, milled 0n the end when used as afulcrum and rivet, in combination with the levers D and D and rope L,for the purpose specified;
